["Journal of Law and Society, Volume 48, Issue 1, Page 106-119, March 2021. ", "\nAbstract\nIn a jurisdiction without a codified constitution clearly demarcating the role of the courts, and given the centrality of the principle of parliamentary sovereignty to the United Kingdom's constitutional framework, criticism of the courts for overstepping the mark – particularly in politically contentious cases – is par for the course. In their 2019 article, Professors David Campbell and James Allan offer a criticism of the Supreme Court for what they describe as its surreptitious creation of judicial supremacy at the expense of parliamentary sovereignty. In support of their claim, the authors examine two particularly significant judgments: R (Miller and another) v. Secretary of State for Exiting the European Union and Re Northern Ireland Human Rights Commission's Application for Judicial Review. This reply discusses several problematic aspects of the authors’ critique of those judgments, demonstrating that, contrary to the authors’ claims, these cases do not provide evidence of a surreptitious attempt by the Supreme Court to expand its power.\n"]
